CODE COMPLIANT CONTINUOUSLY INSULATED WALL ASSEMBLY:
THERMAL & AIR BARRIER WALL SYSTEM with A RAIN SCREEN
ATTACHMENT SYSTEM for EXTERIOR SIDING or CLADDING PANELS
SPEC NOTE:
This guide specification is intended for use of a code compliant,
continuously insulated, wall assembly with a thermally broken cold
formed horizontal metal support/attachment system over 25 PSI
rigid foam insulation to provide a substrate for veneer panel
attachment.
Horizontal girts may be spaced up to 36 inches on center
vertically (depending on cladding weight & design wind pressures)
and support claddings that weight under 9 pounds per square foot.
The maximum allowable spacing and dead load is determined per
project. This is a function of the live load plus the dead load
being equal to less-than the allowable load per wall anchor.
Spacing and maximum loads are typically determined by the
manufacturer.
Make any required selections, such as insulation thickness, board
sizes, etc. where selection is indicated with an [OR] statement,
select the appropriate paragraph and delete the inappropriate
statement. Delete all SPEC NOTEs and [OR] statements prior to
final publication.
DISCLAIMER: The manufacturer has reviewed the product information contained in
this guide specification. The information is organized and
presented to assist the specification writer working on a
construction project to select the appropriate products and to
save time in writing the project specification Section. The

members and anchorage have been installed within thermal wall system alignment
tolerances and requirements.
2.
Verify that substrate surfaces to receive spray polyurethane foam are free of frost, oil,
grease, oxidation, dirt, loose paint, loose scale, or other deleterious material that would
impair bond
3.
Verify that items required to penetrate thermal wall system are placed and penetration
gaps and cracks are properly sealed before installing spray polyurethane foam.
4.
Do not proceed with installation until unsatisfactory conditions have been corrected.
5.
Ensure weather-resistant barrier (WRB) is installed in conformance with WRB
manufacturer’s instructions and discontinuities in WRB are properly flashed and sealed
prior to installing support framing and attachment system.
B.
Field verify architectural details and mechanical and electrical requirements prior to commencing
installation.
C.
Commencement of installation constitutes acceptance of existing conditions and acceptance of
responsibility for satisfactory performance.
3.2 INSULATION BOARD INSTALLATION
A.
Do not install more insulation than can be permanently fastened with vertical cold-formed steel
box girts in the same day. Do not leave insulation overnight or for extended periods that is not
permanently fastened to building substructure with vertical girts.
B.
Install insulation in accordance with manufacturer's recommendations.
C.
Temporary Fastening: Temporarily fasten rigid insulation panels to exterior face of exterior metal
stud wall framing. Abut panels tightly together and around openings and penetrations.
1.
Install panels horizontally with blue aluminum facing to exterior. Use maximum panel
lengths to minimize number of joints. Locate edge joints parallel to and on framing.
Center end joints over supports and stagger in each course. Provide additional framing
wherever panel joints do not bear against framing, plates or sill members.
2.
Fasten rigid insulation panels to each support with temporary fasteners, a single row of
one fastener at each stud framing member. Set back corner fasteners by 3/8 inch from
edges and ends of panel units. Drive fasteners to bear tight and flush with surface of
insulation. Do not overdrive or tear aluminum skin of insulation. [Perimeter fasteners can
be detailed to bridge gap of abutting board joints due to 1.75 inch diameter washer used
to fasten board to studs. Maximum of 2 board joints may be bridged per fastener.]
3.
Install flashing joint tape at end and edge joints using sufficient hand pressure to ensure
seal and in accordance with rigid insulation manufacturer's joint sealing recommendations.

3.3 COLD-FORMED METAL FRAMING INSTALLATION
A.
Preparation:
1.
B.
Verify horizontal girt spacing and framing clearances relative to studs or other points of
attachment.
Installation
1.
Use laser or chalk line to mark starting height of horizontal girt.
2.
Mount stiffened horizontal girts, fastened up to 36 inches on center (as determined by the
manufactures engineering calculations) overtop of installed rigid insulation, using one selftapping screw for each attachment hole at spacing indicated on engineering calculations.
a.
Check plumb of horizontal girts both parallel and perpendicular to the structure.
b.
Tighten screws that attach horizontal girt through insulation to substructure to a
snug tight condition and not stripped. If installed using hand tools, verify for each
installer at beginning of project using snug-tight criteria. Do not use stripped holes.
c.
Where obstructions are present and unavoidable (i.e. window openings), use
laser or chalk line to restart girt.
d.
The cavity must be clear and free from air flow and drainage obstructions.
e.
Use shearing instruments (i.e. snips, nibbler, etc.) for cutting metal framing
components. Saws are not recommended, as the sparks produced during cutting
will damage the anti-corrosion coating. If sparks are generated during cutting, be
sure the portion of the component to be installed on the building is protected from
sparks and that any stockpile near the cutting station is also protected.
